tuberant, bituberculate (a well developed flattened nodule at 

 anterior extremity of each pectoral ridge); pectoral ridges strongly 

 developed; intercoxal part wide anteriorly, lightlj^ sulcate on 

 base. Anterior tibiie rather narrow, strongly 3-dentate; inner 

 apical spine long, curved, obtuse (not incrassate) at apex. Black; 

 base of mandibles, labrum and legs piceous-red; anterior tibiae 

 darker than others. [The type ((J) is from Townsville.] Length 

 8-9-5, breadth 2-2-2-5 mm. 



Hab.—Q.: Townsville (Dodd) — N.S.W. : Clarence River (Lea) 

 — N.W. Australia (Macleay Coll.). 



Intermediate between C. australasice, Bohem., and C. lepida, 

 Putz., but rather allied to C. lepida, from which it differs by its 

 head wider, more depressed, supra-antennal plates more strongly 

 rounded externally, clypeus less deeply emarginate; prothorax 

 more subquadrate, less narrowed to apex, anterior angles more 

 strongly marked; elytra with humeral carina far more strongly 

 developed and formed from the eighth interstice only without 

 support from seventh ; the pectoral nodules nearer together ; 

 anterior tibiae with external teeth more strongly developed, 

 especially the upper one, which is surmounted by a very small 

 prominence, the inner apical spine of male more slender and less 

 obtuse at apex. From C. australasice it differs by the presence 

 of the pectoral nodules in the male; prothorax with sides more 

 rounded, anterior angles more marked ; anterior tibia3 more 

 slender and less strongly dentate and with inner apical spine 

 longer and less pointed at apex; clypeus less strongly emarginate, 

 4fec. From C. isogona, Putz., a species I do not know, C. pecto- 

 noda should differ by colour, and by more strongly dentate 

 anterior tibiae. 



Note. — G. pectonoda is the species I have mentioned as C. aus- 

 tralasice var.* I seem to have confused two species under, this 

 heading, with the result that my remark in regard to the varia- 

 tion in the depth of the emargination of the clypeus is mislead- 

 ing. Four of the specimens (^ and 9) from N.W. Australia
